Less than 10 inches. Clearly, I'm not man enough. Where's my Superman cape? Jeez, you all are puny-ass dudes aren't ya? Except mdonley, of course, who is quite obviously a god among men. Or a liar. Barrel-chested, I guess. To be fair, my colon is well over a rod. Admit it. You made this shit up so we'd post measurements. I did not. It was on Radio 2 this afternoon. Any study that reported on positioning or dimensions of the adult male NAC was included in our review.
Important structural measures are described using means and normal ranges. Key ratios are summarized using mean and standard deviation SD. Comparisons of key measures and ratios, by ethnicity Caucasian vs others , age group, and BMI category, were conducted using t test and analysis of variance ANOVA as appropriate.
Resulting P values are presented unadjusted for multiple comparisons. A total of male patients were recruited for this study, representing individual nipples. The average age was 57 years range, years. Most patients were Caucasian British and Western European.
Most patients had a BMI in the normal or overweight categories. The mean BMI was These data are summarized in Table 1. Height ranged from cm to cm with an average of cm. Our data are presented in millimeters mm , accurate to 1 decimal place.
The average NAC diameter was Average nipple diameter was 6. There were no statistically significant differences in these measurements comparing left and right sides. The average ratio of the diameters of the nipple to areola was 0.
The average internipple distance measured taut across the chest was The ratio between this distance and the average chest circumference was, on average, 0. The ratio between the internipple distance and the distance between the anterior axillary folds was 0. These data are summarized in Tables 2 and 3. This ranged from 0. Although fewer men than women undergo surgery to the breast, there is a growing awareness of the opportunities for enhancing the appearance of the male chest wall.
With the ever-increasing availability of information on surgical solutions to aesthetic issues, male patients are likely to become ever more critical about the outcomes.
Placing the NAC in the correct position on the chest wall is important to ensure a satisfactory outcome after surgery to the male chest wall. Therefore, defining the normal parameters for the adult male is likely to become increasingly relevant in future. The main aim of this study was to look at how surgeons can place the NAC correctly after surgery to address gross preexisting malposition or absence.
We were able to identify nine previous studies that examined aspects of the normal parameters of the male NAC or made recommendations about the ideal position for the NAC. Most of these included only small numbers of young males—the oldest patient in these studies was 54 years. By comparison, our study includes the largest number of normal male patients and the widest range in age.
For example, Kornstein and Cinelli 11 reported a position for the NAC which is 1 to 2 finger breadths cephalad to the intersection of the breast meridian line with the inferolateral border of pectoralis major muscle. They also recommended a NAC diameter of between 25 and 35 mm. They suggested that the male internipple distance should be 22 cm and sternal notch to nipple to be 21 cm.
Beckenstein et al recommended a SNND of 20 cm and commented that earlier suggestions for placement of the NAC created nipples that were too inferior and medial. Beer et al 2 suggested a SNND of 20 cm and a midsternal line to nipple distance of Shulman et al 10 reported a SNND of All of these measurements lie within the range obtained for our own study suggesting that our own results are broadly correct.
Importantly, analysis of our results according to age and ethnic group showed that the sternal-notch to nipple distances do not change with either age or ethnic group. All measurements were taken with the patient upright and it was felt that this position was most relevant in terms of day-to-day appearance.
In addition, most surgery to the breast is performed with the patient head up to some degree and therefore outcomes would not be significantly affected by using only measurements obtained with the patient in the upright position. In terms of NAC dimensions. Previous studies have reported NAC diameters of between 23 mm and 28 mm. Our own study found an average NAC diameter of Previous studies have also reported nipple diameters of between 5 mm and 6. Our study found an average nipple diameter of 6.
There was no significant change in NAC dimension with age. This suggests that surgeons can be confident in selecting a specific NAC and nipple diameter for all their male patients—regardless of age and ethnic origin.
From our own study, we recommend a NAC diameter of approximately Unfortunately, selection of the ideal position for the NAC is more complicated. However, we feel that using ratios may be better since this helps to accommodate differences in the diameter of the chest. A few previous studies have used a similar approach. For example, Shulman used the number 0. Similarly, Murphy suggested using 0.
Interestingly, using the same calculations to obtain the multiplier, our study found a ratio of 0. Others, such as Atiyeh et al, 15 used reverse calculations based on the measurement of the distances between the umbilicus, axillary folds, and sternal notch to deduce the IND and vertical position of the NAC. While elegant, we felt that the use of such coordinates adds a layer of unnecessary complexity.
Moreover, we feel that relying on the umbilicus as a marker can introduce significant inaccuracies—especially with the increasing incidence of obesity. Therefore, use of their technique should really be limited to young, fit, nonobese individuals—who are the group least likely to request surgery to the NAC.
In fact, the main age groups in our study years showed little difference in the ratio 0. The validity of these values was confirmed with statistical analysis. Equations were then derived, using this analysis, to determine nipple position in males. We have determined the nipple position in males to be approximately 20 cm from the sternal notch and 18 cm from the midclavicular line. The ideal nipple-to-nipple distance is 21 cm. They found that the nerves spread out more widely in women than men.

These glands produce a secretion called lipoid fluid to help keep the entire areola and nipple area more lubricated and comfortable.
